Every gun is going to shoot different, if you have any friends that have different chokes try those out with some cheap low brass shells at 25-30yds. Use some large pieces of card board or butcher paper to be able to see the exact center of your pattern. You can get a good idea from this and not have to spend a ton of money on turkey loads. I would suggest starting with the Mag-Blend or HEVI-13 #7 if your looking for high numbers. Most people seem to be getting the best outta these two loads.
